The Bacterium Empire Series are the main bosses in Konami's Gradius video games. Big Core serves as the standardized design, with every other ship following the same principles: A central power core protected by a set of ablative barriers. Sometimes following a famous on-screen prompt to SHOOT THE CORE!, the player's ship must destroy the barriers, then the power core, in order to defeat the boss, all while dodging enough weapon's fire to typically fill the game screen. SHOOT THE CORE! or the variation DESTROY THE CORE! has become something of a catch-phrase among fans of the game.
This card has two more advanced and powerful versions of itself known as B.E.S. Big Core MK-2 and B.E.S. Big Core MK-3.
Even though this card is titled 'Big Core', it does not have the largest attack among the Cores.
On the artwork, three shields protecting the core can be seen, perhaps representing the three counters placed on this card when summoned.

Previously Official Rulings
Boss Rush: "Boss Rush" must be face-up on the field when the "B.E.S." or "Big Core" monster is destroyed for you to use its effect. If the monster is destroyed, and then afterwards you activate "Boss Rush", you do not get to Special Summon for that monster's destruction.
Heavy Mech Support Platform: If "Heavy Mech Support Platform" is equipped to "Big Core" or "Reflect Bounder" and they would be destroyed by their effect, "Heavy Mech Support Platform" is destroyed instead.
Last Turn: If your opponent activates "Last Turn" and you Special Summon a monster that can attack twice, it can attack twice during the special Battle Phase (important if the opponent had a monster like "Big Core").
